"Stone in the frame"

[Frater Yechidah]

Hey all,

Does anyone have a picture of Dee's "stone in the frame", which he used with Saul and the first session with Kelley?

The diagram shows a globe with four legs, with a cross on top.

For clarity, I'm interested in a picture of the real thing, not the diagram, assuming, of course, it has survived. I believe I've seen modern ones that employ this design, but can't seem to find any images of them at the moment.

Thanks.

LVX,
Yechidah.
